Issue

  • New PVC create operation fails with following error:
time="2022-12-15T14:53:39Z" level=error
msg="GRPC error: rpc error: code = Unknown desc = no available backends for storage class sc-ontap-nas-eco"
requestID=8fda9a5c-7bdc-4ebb-99a7-972449729870 requestSource=CSI
time="2022-12-15T14:54:03Z" level=error msg="Invalid backend
state." expectedState=online/deleting requestID=ae514701-44e9-4c42-9956-1d0fced1d14b requestSource=Periodic
state=failed
 
  • Viewing the backend shows failed state
[admin@netapp.com trident-installer-21.10.1]$ ./tridentctl  get backends -n trident
+-------------------------------+-------------------+--------------------------------------+--------+---------+
|             NAME              |  STORAGE DRIVER   |                 UUID                 | STATE  | VOLUMES |
+-------------------------------+-------------------+--------------------------------------+--------+---------+
| ontap-nas-eco_pn8-st-nfiled04 | ontap-nas-economy | 471ac060-2c73-4e37-9649-6670a8964418 | failed |       2 |
+-------------------------------+-------------------+--------------------------------------+--------+---------+
 
Note: this can also happen even if backend is showing online.  Trident does not actively monitor and is updated when an action refreshes status
  • Trident controller pod not running due to Registry server being down internally
